Great video John! You can make 56 minutes go like a breeze because your content is very interesting and paced brilliantly.
Feedback:
-Please please keep the CRT shots, they provide brilliant context as to how the pixels and polygons looked on the TVs of the time. Seeing them immediately took me back to the era in a way that complimented the full-screen video content.
-Your research as always, is brilliant. I remember the disappointent at the Sega Saturn port - not to mention confusion, when Exhumed (Powerslave), Duke Nukem and Quake proved what the system was really capable of. Its fascinating to learn more about the background to this.
-I really like how you played with the structure of your video in an unexpected way, going for quality-of-release order rather than chronological, and also taking time to include Doom 64 while making it specificially clear why it doesn't exactly fit in. Your structure worked brilliantly here - it avoided repetition, provided a clear sequence of advancement, and allowed us to see the gradual increase in quality of each port. Great stuff!
-I know your time investment for this videos is probably already huge, but if there were attached companion videos covering linked content, such as the really obscure ports and fan projects you mentioned at the end, I would have immediately clicked on them to watch. Again, this is more of a wishlist thing, as I know the main video would have taken you long enough to make and was absolutely brimming with content in of itself.
Great work!
